TO ALL WHOM IT vMAY CONCERN:

Be :'t known that we, GEORGE HARSIN and C. 'LS-ANDERS, of Kirkville, inthe county of Wapello, and State of Iowa, have invented a. new anduseful Improvement in Machines for Shearing Sl1eep;'and 'we do herebydeclare that tbc following is a full, clear, and exact description ofthe same, reference being had t the annexed drawings, makingvpart ofthis specification, in which Figure 1 is a side elevation.

Figurc 2.is an elevation of the shears. v

Figure 3 a longitudinal section of' thcvpoint of thestock and shears;and.'

Figure '4 asimilar section ofthe butt of thc stock.

The same letters in all the figures are used to indicate identicalparts.

In the annexed drawings, A, A1, and A? are the posts, to which theshearing-mechanism is attached by cords B and B.

C is the cutter, and D a table, upon which the sheep to besheared isplaced, the sheep being rested against l the knee of the operator, whosefoot should be placed on the table, whilewith his right hand he directsthe cutter, ivith the left rolling backthe eece.

The. cutter is constructed as follows:

C1 is achambered wooden or metallic stock, constructed to receive theshearing-mechanism, which is driven by the band B, which enters thestockl through a glass thimble placed in the end'tliereof to preventfriction. This band passes arounda pulley, G, pivoted to the stock, andhaving an eccentric wrist-pin, G', which is received in a. slot in theend of the arm H, attached to an oscillating cutter, I, constructed, asrepresented, vi'ith knives shaped as shown, and sharpened upon theedges. This oscillating cutter is pivoteclto the stationary cutter K,constructed with the same-kind of projections and cutting-edges, the twosets of cutters acting upon the same principle as the knives of n.harvester, forming, with the oscillation of the blade I, shears to cutthe fleece as the point is carried along thebody of the sheep.

The set-screw I" is intended to keep the blades in clos-e contact.

'Ihe cutter is attached to the cord B,fastened to the eye-holt C3. .'Theoscillating knife is driven by the band or cord B, which .passes overthe driving-pulley L, which is turned by hand or other power. This bandis carried over the pulley M, and thenl through the thmble C2, andaround the pulley Ggwithin the stock, and then back through the thimbleand over thc pulley N to the driving-wheel. The cord B attached te thestock is carried under the pulley O, thence up over the pulley P, andhas a. weight, E, attached to the loose end thereof.V As the cutter ismoved, this cord maintains the tension of the belt, on which is placeda. tensiontveight, F, fastened to a running sheave,vu'hich, when thebelt is slacked, maintains it tantly on the pulleys,

.so that the cutter may be moved as fur as may be necessary withfiutaffecting the movement of the knife I.

What we claim as .our invention, and desire to secure by Letters Patent,is v l'. In combination with thercutt'er C, the belt B and cord B',running over pulleys, and' kept taut by weights, arranged to operatesubstantially as and for the purpose set forth.

2. The combination, in a sheep-shearing machine, of a stationary-blade,K, und oscillating blade I, constructed and arranged, in relation to oneanother, substantially as set' forth.

3. The arrangement of the pulley G, havinga wrist-pin, G, slotted arm H,oscillating cutter I, and stay' tionary knife K, within the hollor caseGf, substantiallyv as and for the purpose set forth.

In testimony whereof, we have signed our names toz'tzhis specificationin the presence of two subscribing witnesses.

y C. T. SANDERS.
